.SH Synopsis
                             std::char_traits<char32_t>::eof

   static int_type eof();  (constexpr since C++11)
                           (noexcept since C++11)

   Returns a value not equivalent to any valid value of type char_type.

   See CharTraits for the general requirements on character traits for X::eof.

.SH Parameters

.SH Return value

                   char_type                    eof()
                  char        EOF
                  wchar_t     WEOF
                  char8_t     an implementation-defined constant that
                              cannot appear as a valid UTF-8 code unit
                  char16_t    an implementation-defined constant that
                              cannot appear as a valid UTF-16 code unit
                  char32_t    an implementation-defined constant that
                              cannot appear as a Unicode code point

.SH Complexity

   Constant.
